Ezra 10:3

Now, therefore, let us make a covenant with our God, by obligating themselves before God with a solemn vow, to put away all the wives, by an absolute divorce, and such as are born of them, the children of such mixed marriages, according to the counsel of my lord, and of those that tremble at the commandment of our God, the will and the precepts of the Lord being interpreted by the spiritual leaders of the people; and let it be done according to the Law, rather, "it shall happen according to the Law," as explained by Ezra and his colleagues.
